摘　　要：基于下沟煤矿综放工作面煤层自燃规律研究基础上,采取加快工作面推进速度、采空区注氮、采空区灌浆、两端头压土袋墙及喷洒阻化剂和建立束管监测系统对综放工作面采空区有害气体进行连续监测等煤层自燃综合防治措施,有效地防止了煤层自燃。Based on the coal self-ignition rule of coalface with top-coal caving in Xiagou mine, comprehensive preventive health measures are taken, such as picking up coalface advancing speed and infusing nirtogen to the waste and grouting the waste and pressing soil bag wall and insufflating negative catalyzer on the two sides of coalface and building the beam tube system monitoring the noxious gas from the waste of coalface with top-coal caving, and so on, to prevent coal seam from self-ignition effectively.
